## Abstract

A showerhead having a control assembly is disclosed. The showerhead includes a head portion operably connected to a showerhead engine, the engine including a plurality of nozzles in fluid communication with the head portion and a handle fluidly connected to a water source and defining a flow path between the water source and the head portion. The control assembly is positioned within the flow path of the handle and is operable to vary a flow volume from the water source to the head portion.

a valve operably connected to the actuator and received within the valve cavity, wherein as the actuator moves from the first position to the second position, the valve rotates within the valve cavity from an open position to a closed position; and
a valve driver positioned between the actuator and the valve and configured to convert arcuate motion of the actuator into a rotational movement of the valve;
wherein a portion of the valve driver is received in the slot and slides within the slot in the longitudinal direction of the pause assembly as the actuator moves from the first position to the second position.

### Claim 2 (depends on 1)

The showerhead of claim 1, wherein the valve is a ball valve comprising:
a first flow path; and
a second flow path; wherein
in the open positon, the first flow path is fluidly aligned with the flow path and in fluid communication with the head portion and the water source; and
in the closed positon, the second flow path is fluidly aligned with the flow path and in fluid communication with the head portion and the water source.

### Claim 3 (depends on 2)

The showerhead of claim 2, wherein the second flow path has a reduced diameter relative to, and is oriented perpendicular to, the first flow path.

### Claim 4 (depends on 1)

The showerhead of claim 1, wherein the valve driver is removably attached to the valve.

### Claim 5 (depends on 1)

The showerhead of claim 1, wherein:
the valve driver includes a disc that is rotatable about its central axis;
the portion of the valve driver received in the slot comprises a boss laterally offset from the central axis of the disc and extending outwards and upwards from a top surface of the disc; and
the valve driver includes a keying feature extending from a bottom surface of the valve driver and shaped to engage the valve.

### Claim 6 (depends on 1)

The showerhead of claim 1, wherein
the valve driver is rotatably seated in the outer surface of the valve housing and an aperture is defined through a central region of the valve driver.

### Claim 7 (depends on 6)

The showerhead of claim 6, wherein the valve driver is coupled to the actuator such that movement of the actuator along the outer surface of the valve housing causes the valve driver to rotate relative to the actuator and the valve housing.

### Claim 8 (depends on 6)

The showerhead of claim 6, further comprising a fastener extending through the aperture and fastening the valve driver to the valve.

### Claim 9

A showerhead comprising:
a plurality of nozzles;
a handle configured to be fluidly connected to a water source, the handle defining a flow path between the water source and the plurality of nozzles; and
a pause assembly positioned at least partially within the flow path of the handle and operable to vary the flow of fluid from the water source to the plurality of nozzles, the pause assembly comprising:
a valve housing including a fluid inlet and a fluid outlet;
a valve assembly positioned at least partially within the valve housing, the valve assembly movable between a plurality of positions to vary fluid flow through the valve housing between the fluid inlet and the fluid outlet; and
an actuator movably coupled to the valve housing such that movement of the actuator relative to the valve housing moves the valve assembly between the plurality of positions, the actuator rotatable about a longitudinal axis of the handle to move the valve assembly in a different type of motion, the actuator defining a slot extending lengthwise along a longitudinal direction of the pause assembly;
wherein a portion of the valve assembly is received in the slot and slides within the slot in the longitudinal direction of the pause assembly as the actuator moves the valve assembly between the plurality of positions.

### Claim 10 (depends on 9)

The showerhead of claim 9, wherein the valve assembly comprises:
